Answer 1

Answer on Question #42323 - Chemistry - Inorganic Chemistry

Question:

What quantity of 0.25 M HNO₃ can be neutralized by 0.10 liters of 0.50 M NaOH?

Solution:

The equation is:

$$\mathrm{HNO_3} + \mathrm{NaOH} = \mathrm{NaNO_3} + \mathrm{H_2O}$$

0.1 liter of 0.50 M NaOH solution contains $0.1 * 0.5 = 0.05$ moles of NaOH

The quantity of $\mathrm{HNO_3}$ needed to neutralize NaOH is the same to the quantity of NaOH, 0.05 moles.

The quantity of $\mathrm{HNO_3}$ solution needed is $\frac{0.05}{0.25} = 0.2$ l

Answer: 0.2 liters
